BOILER-STAND.

Specification of Letters Patent. Patented 13, 141;, 1913,

Serial No. 624,4Q8.

Application filed May 1, 1911.

11 of the ring in an arc concentric with the ring. Each lug has slightlysloping sides 13 which taper toward one end of the lug and a flat top 14to give close engagement to the corresponding parts of the notches 9 and10 of the legs B. A pair of lugs is provided for the attachment of eachleg B in its normal position. One lug 15 being on top of the body 11 ofthe ring and the other lug 16 similar in shape lying upon the oppositeside of the ring and slightly outside of the upper lug 15.

The recess To all whom it may concern:

Be it known that 1, THOMAS OCoNNnLL, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented a new and useful Improvement in Boiler-Stands, of whichthe following is a specification.

My invention relates to improvements in boiler stands for hot waterboilers and its object is to provide a stand which may be readilyassembled to receive a boiler and which may be readily adjusted to beused in connection with the different sizes of standard boilers. I havesecured these results in a device which is very simple in constructionand has no bolts, screws nor loose adjustable parts to become lost orout of order.

In the drawings with which I have illustrated my device and which formpart of my specification, Figure 1 is an elevation of my boiler stand;Fig. 2 is a plan of the connector ring; Fig. 3 is a section of the ringon the line AA of Fig. 2; Fig. 1 illustrates a similar section with thering reversed; Fig. 5 illustrates the position of the legs when used inconnection with the ring in the position shown in Figs. 3 and 4: foradjustment, and Fig. 6 illustrates an alternative construct-ion of theconnector ring.

In the above drawings 1 have shown a boiler stand made up of three legsB and a connector C joining the legs and holding them in position asillustrated in Fig. 1. Each leg B is formed of convenient shape havingan upper extremity notched at the point 2 to receive the rim of a hotwater boiler, while the lower extremity of the leg has a partly roundedsurface 3 allowing the angular positioning of the leg adjusting it todifferent sizes of boilers without presenting a sharp corner on thesupport.

A rim a and apertured web 5 allow a strong light construction of theleg. On its inner side the leg is formed with a recess 6 between thelugs 7 and 8. Within the recess 6 in its sides are engaging notches 9and 10. The lugs 7 and 8 are reinforced laterally about the notches 9and 10 to give them greater bearing surface and each is substantially inthe form of a longitudinally disposed hook.

The connector C as illustrated has the form of a flat ring 11 havingoblong lugs 12 formed integral with its upper and lower surfaces. In theform illustrated in Fig. 2 the lugs 12 are cast integral with the body 6in the legs B has a width suflicient to slip over the body 11 of thering allowing the notches 9 and 10 to be brought into a position to slipover the lugs 15 and 16 in the position shown in Fig. 3 where they arerigidly engaged by the slight taper of the lugs, thus holding the legs Bin firm connection with the connector C. Three pairs of lugs 15 and 16are provided on the ring 11 allowing the positioning of the three legs Bto form a stand of the form shown in Fig. 1 which is accommodated to thesmallest size of boiler to which the stand is adjustable. By turning thering 11 over, the lugs 16 lie upon its upper surface as shown in Fig. 4in position to engage the notch 9 when the lug 15 lying below the lug 16engages the notch 10. This reversal of the lugs in the notches 9 and 10throws the notch 10 to a position on the lug 15 causing the rotation ofthe leg B to the position 17 shown in dotted lines in Fig. 5.

It is evident that the movement of the upper notch 2 outwardly from thecenter of the rim on each of the legs will increase the boiler diameterwhich the stand is fitted to carry, thus accommodating the stand to twosizes of boilers.

In Fig. 2 I have illustrated lugs 18 and 19 similar in form to lugs 15and 16 but positioned near the outer circumference of the ring 11 thuslocating the leg B upon a circle of greater diameter. This diameter maybe made such that in the normal position of the ring 11 a larger sizedboiler will be accommodated by the stand than in the reversed positionof the ring when using the lugs 15 and 16. The lugs 18 and 19 are formedwith the lower lugs 19 extending slightly beyond the lugs 18 as shown inFig. 2 and by reversing the ring 11 the legs may be rotated from theirnormal position as illustrated in Fig. 5 again increasing the diameterof the boiler which may be accommodated.

It is evident that the number of different sizes to which my form ofstand may be adjusted is limited only by the number of pairs of lugswhich may be placed upon the ring 11 and that this number of lugs may beincreased by increasing the relative diameter of the ring. For ordinarycommercial purposes the adjustment to four sizes of boilers issuflicient and may be eificiently secured by a connector and leg havingthe proportions shown by which a li 'ht rigid stand is secured havinggreat rigidity and strength.

In ig. 6 I have illustrated an alternative form of engaging lug 21 whichis placed upon the ring 11 in a spiral position. The opposite lug 22 ofthe pair is formed with a spiral in the opposite direction intersectingthe line of the lug 21 near its middle point. The position. of the legsB having their notches engaging the lugs 21 and 22 is changed by movingthe legs along the lugs 21 and 22 thus causing the engaging notches 9and 10 to assume diiferent relative position laterally.

The form of connector ring C may be varied, the essential feature beinga pair of engaging faces or lugs to which are fitted correspondinggrooves or notches in the leg parts of the stand in such a manner as toproduce a rigid stand. The same result may be secured by using a ringhaving segments formed at an angle to the plane of the ring whereby theleg parts sliding upon the lugs will be rotated when moved from one segment to another of the rings. The design of the parts of this inventionand particularly although not exclusively the ring permits of stampingwhich is a material advantage in the fabrication of the parts incommercial practice.

In accordance with the patent statutes I have described the principlesof operation of my invention together with the apparatus which I nowconsider to represent the best embodiment thereof but I desire to haveit understood that the construction shown is only illustrative and thatthe invention can be carried out by other means and applied to usesother than those above set forth within the scope of the followingclaims.

Having described my invention, what I claim as new and desire to protectby Letters Patent is 1. A boiler stand comprising a plurality of legseach having upper and lower engaging notches in fixed position andopposed to each other, and a connector having upper and lower lugsadapted to engage said notches on said leg to fix them rigidly, saidlugs being positioned to adjust said legs to one size of boiler in oneposition of said connector and to another size of boiler in the reversedposition of said connector.

2. A boiler stand comprising a plurality of leg parts in fixed positionthereon having engaging notches, a connector ring adapted to carry saidleg parts and having a pair of integral lugs disposed on opposite sidesof said ring at different distances from the center of said stand toengage each of said leg parts to hold it in one position in the normalposition of said ring and in another position in a reversed position ofsaid ring.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
